The Quadratic Formula

Solving for x in a given polynomial equation “ax2 + bx + c =0”, can be solved by factoring the equation. 

Another way is by using Quadratic formula, where it is derived in the process of completing the square. 

Thus, $$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$$

where x = solutions of the equation

          a, b, c = numerical coefficient 


Solve for x using Quadratic Formula given : 6x2 + 11x - 35 = 0
